Use and Safety
Please read this manual carefully to insure safe usage
and understanding of maintenance instructions.
Congratulations on your purchase of a Drive wheel-
chair. Drive wheelchairs are a product of quality
engineering and are manufactured to meet our own
highly rigid specifications and will surpass all your
expectations.
CAUTION:
Stability - Wheelchair is designed to be safe and stable as
long as center of gravity is maintained while going about
normal activities. Care must be taken while performing
activities that shift your center of gravity in the chair.
Never reach so far that require you to shift in the seat or
bend over out of the chair. When you have to reach for
objects that require you to lean, be certain front casters
are pointing in a forward position that extends the wheel
base and will stabilize the chair.
Ramps - Be sure of your own capabilities, limitations and
strength before attempting to go up a ramp. Correct
techniques on ramp negotiation should be shown to you
by a qualified professional. Assistance is recommended
when going up or down inclines greater than 10o. If you
must stop on an incline, avoid sudden, abrupt movement
when you resume movement. Because of backward
angle of the chair, sudden abrupt movement could cause
instability. Attempting to use the wheel lock brakes could
result in accidental locking, tipping to one side, or cause a
sudden stop. Avoid changing direction when going down
an incline, as this could result in instability of tipping over.
WHEEL LOCKS - Engage both wheel locks before
getting in or out of chair, leaning forward in chair, or
while in an elevator or wheelchair lift. Proper adjust-
ment of wheel lock is at least 1/8” when locked. Locks
are engaged by pushing handle completely forward.
Adjustments to locks are made by loosening or tight-
ening nut on the carriage bolt. Embed lock shoe at
least 1/8” by sliding clamp toward rear wheel while
handle is engaged in locked position. Tighten nut and
bolt to secure in position. Test for correct locking
action before actual use.
TIRES - Solid rubber tires need minimal mainte-
nance, but should be cleaned occasionally with a
damp cloth. Replace if tires become severely worn
or cracking appears.
FRONT CASTERS - Front casters and associated
mounting hardware should be inspected at least
once a month to ensure proper tightness. Lubricate
the casters by removing fork and greasing caster
stem bearings. Lubricate wheel bearings by remov-
ing wheel from fork. Reassemble fork and wheel by
tightening nuts until no play remains, but wheels roll
freely. If nut is too loose, caster will shimmy, if too
tight, chair will be hard to steer.

en axle bolt slightly. Test for proper tightness by
learning chair to one side and spin adjusted wheel.
GENERALCARE - Wipe chrome parts with a clean,
soft cloth at least once a week. All metal parts can
be cleaned with auto wax or similar poducts. If

tip over. When trying to extend arms over back,
only reach as far as your arm can extend without
having to alter your seating position.
DO NOT stand on wheelchair.
DO NOT use wheel locks to slow your descent
down an incline.
Abruptly changing directions while going down
an incline could cause instability or possible tip-
ping over.
The Viper Plus GT Full Reclining comes with a “quick
release” rear axle. To adjust the position of the rear
wheel, depress the center hub (figure 1) and the lock
will disengage. Pull the wheel off the frame. Select
the axle position and place the wheel shaft in until
an audible click is heard.
The 3 position front caster can be adjusted for
positioning with the rear wheel. To adjust the front
caster, loosen the bolt (outside of the caster) with an
allen wrench (included). Remove the bolt and axle
and place into the desired position. After the axle
is placed in the new position, turn the allen screw
clockwise to tighten.

To extend the length of the foot plate on the front
riggings, locate the tool free lock release (figure
4). Lift up on the release and locate the push pins
located on both sides of the tubing. Depress the
push pins simultaneously and slide the footplate
to the desired position. The push pins are spring
loaded and will lock into place. Pull down on the
lock release until flush with the tubing. Repeat for
the other side of the rigging.
The Viper Plus GT Full Reclining features an adjust-
able angle back that adjusts from 5 degrees to 20
degrees in 5 degree increments. To adjust the angle,
locate the adjustment flange located at the rear of
the frame under the seat (figure 2). Loosen both of
the bolts with the allen wrench (included). Do not
remove the bolts completely. Repeat for the oppo-
site side of the chair. With the bolts on both sides
loose, slowly pull back on the cane handles (figure
3) until the back is positioned to the desired angle.
When in the correct position, tighten the bolts with
the allen wrench until tight. Repeat for the opposite
side (be sure the angle position in the flange is the
same on both sides).
